Consider this configuration:
ip link add br0 type bridge
ip link add vx0 type vxlan dstport 4789 external
ip link set dev vx0 master br0
bridge vlan del vid 1 dev vx0
ip link add vx1 type vxlan dstport 4790 external
ip link set dev vx1 master br0
root@vsid:/src/iproute2# ./bridge/bridge vlan
port vlan-id
br0 1 PVID Egress Untagged
vx0 None
vx1 1 PVID Egress Untagged
root@vsid:/src/iproute2#
Note the useless and inconsistent empty lines.
root@vsid:/src/iproute2# ./bridge/bridge vlan tunnelshow
port vlan-id tunnel-id
br0
vx0 None
vx1
What's the difference between "None" and ""?
root@vsid:/src/iproute2# ./bridge/bridge -j -p vlan tunnelshow
[ {
"ifname": "br0",
"tunnels": [ ]
},{
"ifname": "vx1",
"tunnels": [ ]
} ]
Why does vx0 appear in normal output and not json output?
Why output an empty list for br0 and vx1?
Fix these inconsistencies and avoid outputting entries with no values. This
makes the behavior consistent with other iproute2 commands, for example
`ip -6 addr`: if an interface doesn't have any ipv6 addresses, it is not
part of the listing.

This series adds support for selecting the offloading mode of a MACsec
interface at link creation time.
Available modes are for now 'off', 'phy' and 'mac', 'off' being the default
when an interface is created.
First patch adds support for MAC offloading.
Last patch allows a user to change the offloading mode at runtime
through a new attribute, `ip link add link ... offload`:
# ip link add link enp1s0 type macsec encrypt on offload off
# ip link add link enp1s0 type macsec encrypt on offload phy

In the commit referenced below, ip link started sending ERSPAN-specific
attributes even for GRE and gretap tunnels. Fix by more carefully
distinguishing between the GRE/tap and ERSPAN modes. Do not show
ERSPAN-related help in GRE/tap mode, likewise do not accept ERSPAN
arguments, or send ERSPAN attributes.
